Black rubber boat trailer rollers, the economical, general-purpose all-rounder that suits most trailers and boats. Rubber rollers grip well, cushion the hull and are the go-to for cost-conscious builds and replacements. Viking Rollers supplies the black rubber range: keel, bow, bilge, Sydney, concave, deep-V and jumbo rollers, self-centre rollers and end caps, to trade and wholesale buyers Australia-wide.
